Because the piston of internal combustion engine works under high temperature and pressure, the requirement of piston is relatively high, so the classification of piston of internal combustion engine is mainly talked about.
1. According to the use of fuel to divide, can be divided into gasoline engine piston, diesel engine piston, day gas piston.
2. According to the material to manufacture piston, can be divided into cast iron piston, steel piston, aluminum alloy piston and combined piston.
3. According to the process of manufacturing piston blank, can be divided into gravity casting piston, extrusion casting piston, forging piston.
4. According to the working conditions of the piston, can be divided into non-pressurized piston and pressurized piston two categories. 5. According to the use of piston, can be divided into car piston, truck piston, motorcycle piston, marine piston, tank piston, tractor piston, lawnmower piston and so on.
